Seven for the Dwarf-lords in their halls of stone, Three Rings for the Elven-kings under the sky, Together they made many artefacts, heirlooms, magic rings and at last they forged nineteen Rings of Power: Seeming to the eyes of many as one both wise and fair, he taught the skilled Elven smiths many crafts, including the art of ring-making. Under the guise of Annatar - 'the Lord of Gifts' - Sauron ventured into the western lands of Middle-earth. Background The Lord of the Rings/ The Hobbit
